Enter your invoice value, labour, and costs to find out what a job actually earned you — per hour, and as a margin.
Most tradespeople have a rough sense of whether a job went well — but very few know their actual profit margin per job. Without this number, you cannot tell which types of work are worth taking, which clients cost you money, or whether your pricing is keeping pace with your costs.
A full diary does not mean a profitable business. A tradesperson charging £500 a day but spending £350 on labour, materials, and travel is making a 30% margin — fine. But if that same job takes twice as long as quoted, the margin collapses to nothing. Tracking profitability per job reveals these patterns.
As a rough guide: below 20% is thin and leaves little room for error. 20–35% is healthy. Above 35% is strong. These are gross margins — they do not account for your overhead and business running costs, which typically add another 10–20% to what you need to cover.
